Original Abstract

The nitrogen short live afterglow was studied in DC flowing regime at wall temperature of liquid nitrogen as a function of oxygen traces concentration. The slight increase of populations of neutral nitrogen N_2 (B ^3 Pi_g) and N_2 (C ^3 Pi_u) states was observed more or less independently on the vibrational level, on the other hand the populations in molecular ion N_2^+ (B ^2 Sigma _u^+) state were strongly quenched by oxygen addition. The maximum of pink afterglow emission time was shifted to the later post-discharge times in the dependence on the electronic state. Besides the nitrogen molecular spectra, the spectrum of NO-beta system was observed. Intensities of these bands increased with increase of decay time, as well as with the increase of oxygen concentration.
